Compare any two graphics cards:
GeForce GTX 460 2GB vs Radeon R9 270
IntroThe GeForce GTX 460 2GB features a GPU clock speed of 675 MHz, and the 2048 MB of GDDR5 memory is set to run at 900 MHz through a 256-bit bus. It also features 336 SPUs, 56 TAUs, and 32 ROPs.Compare those specifications to the Radeon R9 270, which has a GPU core clock speed of 900 MHz, and 2048 MB of GDDR5 memory running at 1400 MHz through a 256-bit bus. It also is comprised of 1280 SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 270 will be 56% faster than the GeForce GTX 460 2GB in general, because of its higher bandwidth. (explain)
Texel RateThe Radeon R9 270 is quite a bit (approximately 90%) faster with regards to anisotropic filtering than the GeForce GTX 460 2GB. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 270 is the winner, and very much so. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
